These Are Powers’s “Silver Lung,” the A side of their debut seven-inch, grabs you from the get-go with a completely diseased guitar riff–a pulsing, mechanical bleat that sounds like a meltdown alert at a nuclear reactor. Formed just this past September, the Brooklyn trio has attracted plenty of attention already, in part because bassist-vocalist Pat Noecker was in the Liars and guitarist-vocalist Anna Barie was in Knife Skills. Like Teenage Jesus & the Jerks, These Are Powers have a postapocalyptic sound that veers between dread and panic, and drummer Ted McGrath plays simple quasi-tribal beats on a kit with no hi-hat, a nod to the early minimalist style of Bob Bert and Ikue Mori. Those aren’t even the only cues the band takes from early New York postpunk and no wave: the seven-inch was mixed and mastered by ex-Voidoid Ivan Julian, and the unsettling black-and-white video for “Silver Lung” looks like an homage to mid-80s Cinema of Transgression heavyweight Richard Kern.
